Overview
YSG-P400 provides RF signal generation from 200 MHz to 40 GHz with −40 to +10 dBm output and switching below 200 µs. Frequency and power sweeps support repeated test sequences in laboratory, manufacturing and field setups.
The OCXO timebase provides ±0.3 ppm frequency stability. Pulse modulation, AM and FM are supported, with 10 MHz reference input/output for synchronization with other instruments.
Additional product details
The YSG-P400 Series is engineered for engineers who need RF signal generation in field-portable form. The YSG-P400 Series covers 200 MHz to 40 GHz and switches in under 200 µs, supporting rapid test sequences in R&D, manufacturing, and field environments.
The YSG-P400 Series OCXO (oven-controlled crystal oscillator) timebase provides ±0.3 ppm stability for repeatable measurements. The YSG-P400 Series also helps diagnose receiver performance issues on site.
